I've been thinking about this subject, off and on, for days. It finally hit me. Rebgold, you are in the business of KNOWING your flavors. You have to in order to do what you do. Most of us don't have the tongue to taste individual flavors in e-liquid, let alone food, and we tend to taste the overall product.
If you really think about it, someone that is a coffee fanatic (maybe a little strong word but gets the point across) has a VERY difficult time finding a coffee vape that they can vape. I think in part because they KNOW what that coffee is supposed to taste like. A tangible flavor that their mind knows for absolute certainty. Their mind cannot be tricked by something that is close.
I know what certain flavors I love are supposed to taste like and trying to find a liquid that imitates them is usually not going to happen. If it is something that I have never eaten? I usually end up liking the liquid or at least am able to give it a fair shot before relegating it to the discard or keep pile.
The more I read the forums, it seems as though those that are in the food/flavor business are the ones that have a harder time with flavors in the liquids they buy from vendors. Wine connoisseurs have trained themselves to pick out the nuances in different wines. They also can spot the different flavors in complex e-liquids. I was always baffled at how people can get one thing on an inhale and something else on the exhale. Heck, I was just happy tasting flavor, Period. Still am.
I get your frustration, but many of us do NOT have that frustration. Does it make it right that, to you, vendors are putting higher prices on "boutique" liquids? Maybe people have a slightly better than average taster and gravitate to something that is a bit more boutique, yet don't have the super taste that someone in the food/flavor business has.
To you it may be crap liquid, to some of us it is the one thing that stands between smoking and not smoking. You are definitely entitled to your opinion and it is a very valid opinion. You have the background. Just please remember, not everyone can taste those flavors with such ease. Most get the general idea by the total package.
